"o a3" it that l JOHN uSGHALL. citizen of the 1 'ii'r l States, residing at Evergreen Park. in county OfaCGOk and *State of -liiinois,=ha e in ented certain new-and useful Improvements in Rotataole Shoe-Heels; and l do hereoy declare the-following to-be a full. clear, and exact description-of the 'invention, such 'll enable others skilled in relates toimprmements in shoe heeis and has for its nbjestjto provide a shoe has in a tread member ntitatable relative tot-he upper crfixedportion ofthe heel for" thefheel causing the same tooperate in acnerds nee w th my invention.

Bdy'said heel comprises the part A 'ivhich is and to the heel portion'o f the-soleB-of the shoe andthetread portion C whlph is rotatahly mounted on thefixed portion A.

The said tread portion G and the lowerend .of the fixed portion A are both relatively trian his sin shape, the corners being widely round edand the sides cnrved aswill more particular appear from Fig. *8 so asto allow it to .simnlate-in appearaneethestandard heel-now-generally employed. LMounted in recesses in the meeting faces 0 f the portipns A and C t-theheel are substantially'triangular plates 'D and E, each havinge relatitely large central opening and three astively large perforations F arranged equispecification of Letters Patent.

distantly from the aXis of the central opening and equi-distantly from each other and in the corner portions are further provided with three smaller perforations G radially equ -distant from the aXis of rotation and equl-distant from each other. The said plates are so mounted in the meeting faces of said' parts A and C as to register with each other axially and peripherally as the edges of the meeting faces of the said portions register with each other. Each of said plates is secured in its recess by means of nails or brads passing through the smaller perforations G and through the portion E and 6 respectively, of the heel, the brads securing the plate '51) passing also through the sole l3 of the shoe and being clenched upon the same in a Well-known manner. Said portion of the heel may be further sccured'to the sole B by short nails or brads in the-usual and well known manner.

'fihrou h the larger perforations in the plate Em the member'C and into the body portion of said-member 'l mount pins H having conical 'or rounded upper ends Which -%roject\from the upper surface of the plate and-are adapted to engage inithe perforaationsiFof the-plate D to hold said plates in register with each other and against relative rotation. Wlfithin the recesses containing said plates D and E I provide central recesses which receivethe disks, which are circuler,,and are-disposed concentric with the .eentral-openings in said-members D and E -andereoflarger diameter than said openings; @Disposd between said disks I and passi through 'the central openings in the plat-e2?) and E is a helical tension spring J secured-at -its respective ends to the'disks I preferably by passingthe ends of-the-sprmg through perforations in said disks and 'clenching them upon the other faces of the latter, it. being understood, however, that the said-ends of said spring may be rigidly secured to said disks in any other suitable manner. The said spring by its tension maintains the faceso'f-the-parts A and-Ger the heeliin close contact and nor- .mally maintains the projecting. end portions of the pins H engaged in the perforations F est Wear may be .with the pins H and tions for the passage of the brads G now of the plate D thereby maintaining the peripheral edges of the portions A and C of the heel in register. The disks I are rotatable relatively to the plates D and E and by exerting a separating force upon said portions A and C of the heel to withdraw the pins H from engagement in the perforations of the plate D the same may be rotated throughan arc of one hundred and twenty degrees whereupon the said pins will again register with and engage in the perforations F of the plate D, and in this position the peripheral edges of the parts A and C of the heel will also again register. By this means that corner of the heel disposed farthest rearwardly and subjectedto the greatturned so as to lie at one of the forward corners of the heel and thus successively each of said corners may be brought into position to be subjected to the greatest wear. Thus the heel is maintained at all times subject to substantially equal wear.

My invention is simple, easily applied and does not produce the so-called freak appearance of the shoe whidh would be objectionable commercially. The clenched ends of the brads securing the plate E to the part C of the heel may be covered by an additional layer of leather L, as shown in Figs. -1 and 2, to prevent said clenched ends be ing worn off and the plate E becoming loose therein.

In assembling the heel, the plates D and E, the spring K and the disks J are first assembled. By then turning said parts relatively to each other through an arc of about one hundred twenty degrees, the perforations for the brads G will be exposed and said brads inserted through all of said perforations. Then the plate D will be mounted in the upper member of the heel and said plates then turned so that their peripheral edges register, with each other. The lower member of the heel, previously equipped provided with perforacarried by and projecting from the plate IE, will be now moved 'to position, receiving said brads and causing the ends of the pins H to enter the. openings in the plates E and D. The brads are then drawn up tight and clenched-and the piece Lmounted'in place. It will be noted that the outer diameter of the spring K is substantially the same as the diameter of the central openings in the plates D and E so that said'sprin consti-' tutes the pivot about which said p ates rotate relatively to each other. The device is thus rendered very light and simple in construction.

I claim as my invention:

1. In a shoe, a heel having a tread portion and a fixed portion rotatable relatively in said to each other, said portions having respectively equal substantially polygonal meeting faces, and provided with interengaging formations adapted. to maintain said faces in register with each other, the formations of at least one member corresponding in number and with the edges of the same and positioned relatively to the latter and the axis of rotation to cause said formations to register after each partial turn of said tread member through a given are, and a spring for normally maintaining the meeting faces of said members in contact and said formations interengaged, said spring constituting the pivot about which said tread member is rotatable.

2. In a shoe, a. substantially triangular heel having equal sides and angles and divided horizontally into two parts, plates mounted in recesses in the meeting faces of said parts and having registering central openings concentric with the axis of the heel, there being three sets of inter-fitting formations in said plates disposed equidistantly from said axis and from each other and arranged to interengage as the peripheral edges of the respective parts of the heel register, a spring for maintaining the meeting faces of said heel parts in contact with each otherpassing through said central openings plates and constituting the pivot about'which the tread member is rotatable, and means rotatable relatively to said plates with which said spring is engaged at its ends.

3. In a shoe, a substantially triangular heel havin equal sides and angles and divided horizontally into two parts, plates mounted in recesses in the meeting faces of Said parts and having registering central openings concentric with the axis of the heel,

there being three sets of interfittin formations in said plates disposed equidistantly from said axis and from each other and ar-' ranged to interengage as the peripheral edges of the respective parts of the heel register, a tension spring for maintaining the meeting faces of said heel parts in contact with each other passing through said central openings in said plates and constituting the pivot about which the tread member is rotatable, and means rotatable relatively to said plates with which said spring is engaged at its ends.

4. In a shoe, a heel divided horizontally into two parts, plates mounted in recesses in through an are equal to that separating con:

Ill

tiguous pairs of said formations, and a name in presence of two subscribing witspring for maintaining the meeting faces of nesses.

said heel parts in contact with each other passing through said central openings in said plates and constituting the pivot about Witnesses:

which the tread member is rotatable. ALBERTSGHEIBLE,

In testimony whereof I have signedmy M. M. BOYLE.
